front bank O2 sensor change
Guys my drivers side O2 sensor keeps triggering check engine. So I think its going out. I understand how to change it but I cannot get to the harness to unplug the old one. I don't want to pull or tug And break something. Is the easiest way to get to that harness is to remove the upper manifold? What have others done for a more simpler install?
